Radon Testing

Service Overview

According to the EPA’s publication, “A Citizen’s Guide to Radon”, Radon is a radioactive gas. It comes from the natural decay of uranium that is found in nearly all soils. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Your home traps radon inside, where it can build up. Any home may have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements.


Radon from soil gas is the main cause of radon problems. Nearly 1 out of every 15 homes in the U.S. is estimated to have elevated radon levels. Elevated levels of radon gas have been found in homes in your state. Contact your state radon office for general information about radon in your area.


While radon problems may be more common in some areas, any home may have a problem. The only way to know about your home’s level of radon is to conduct a radon test. A short-term radon test consists of taking air samples from inside the home during a two day period.  Longer tests can be preformed by to 90 days.  The amount of radon in the air is measured in “picocuries per liter of air,” or “pCi/L.” A radon level of 4 pCi/L or higher should be reduced.

When to Schedule a Radon Test

Testing is the only way to know if you and your family are at risk from radon.

Radon is estimated to cause many thousands of deaths each year. In fact, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.

Who should Attend

No attendance is necessary.  Simply take steps to prevent device interference while the radon test is in progress.

What to Expect

Within 24 hours of the completion of the radon test, you will be provided with a comprehensive report describing the radon level.
